' invented new and useful Improvements in Spinning Machinery, of which the following is a specification.

This invention relates to all doubling, twist-.

in or re arator or s innin machines or fra mes in iivhich he m eiterial under treatment is simultaneously and continuously twisted and wound, and hasfor its object, first, the simplification of the-present usual systems and the abolition of their different inconveniences; second, to. render the work'- ing quite independent of the diameter of the windingthat is to say, to enable the spinning and winding to be equally accomplished large tubes and even on the bare spindle whatever its diameter may be; third, to permit more particularly these results to be attained on frames for roducing weft-cops.

The desired object is attained by 'efiecting the winding in the followin manner: The roving or the like after quitting the drawing and delivery rollers passes in the usual manner through a guide or eye which is situated in a prolongation of the spindle upon which the cop or the like is to be wound. Thence the roving asses under the lower side-of a ring which 1s secured to the spindle in any suitable manner, and consequently rotates at the same speed as the spindle. From this ringthe roving or thread asses upward ver-' tically or at an angle which respective positions of the various parts and passes on to the upper edge of a second and non-rotatable ring which-is situated in such a position that its upper part will always be higher than the lower or under part of the first ring. The second ring has an alternative vertical movement which is determined by the form in which the bobbin or cop is to be built and is transmitted through suitable parts or devices from a rising and falling rail which is operated in a manner as is well understood in connection with spinning-frames. The thread is thenwound onthe spindle, tube, or bobbin. The two rings just described and the axes of which are coincident with the axis of the spindle are of any suitable and desired cross-section and may,-for

and falling rail or equivalent.

will vary with the librium is disturbed in any manner.

iexample, be so shaped as to permit, if neces: saryftheaddition of travelers orother devices of a like nature with a view of increasing the frictional resistance.

The drawings hereunto annexed indicate the improved appliances.

Figure 1 illustrates them in vertical section. Fig. 2 shows them in cross-section along the line a: a: of Fig. 1.

a and 1) indicate the delivery-rollers, c, a thread guide'or eye-of the usual construction situated in a prolongation of the axis of the spindle.

d is the spindle, and e the first ring, which is attached to the spindle by means of the part g. g is an approximately bell-shaped part, the lower part of which is formed to the ring 6, or the ring may be otherwise attached in any suitable manner which willpreserve it in about the position shownrelatively to the spindle. a

his a. non-rotatable ring carried by a part i, by means of which a sultable reciprocating vertical motion can be given to the ring h. The part 'i, which carries the ring h, passes through the ring 6 and is secured to a rising The part i shown is cylindrical; but this can be substituted by any other convenient sup ort. The amount of motion given to the ring i must be sufiicient to enable it to move along the whole length of that part of the spindle upon which the cop or the like is being formed or built.

m indicates the thread or roving; n, the cop in process of formation. The thread m, delivered by a, and 6, passes through the guide 0, under the ring e, up over the ring it, and from there is wound on the spindle d to form a cop. It will thus be seen that the thread under the conditions specified is acted upon as follows: in the direction of rotation,

first, by the friction of the rotatable ring'e,

and, second, by a pull tangential to the diameter of the wound part; in the opposite direction, third, by the air resistance to the ballooned thread, and, fourth, the friction of the fixedring' h. Under these four influences the thread takes up an equilibrated'tension in which it endeavors to remain and to which it will endeavor to return if the equi- For example, the' feeding or delivery of the thread continually tends to diminish this tension,

and a counterbalancing is effected by the Winding or building of the cop or the like.

The dimensions, dispositions, and forms of the diflerent parts and appliances may be modified according to circumstances, as the manner or speed of Working or the like.

Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be performed, I declare that What I claim is In a preparatory or other spinning machine, the combination of a spindle, aring coaxial to and rotating with the spindle, a second ring also coaxial to the spindle, but non-rotatable and movable to and from a plane above that r 5 of said first-named ring, by a movement through the same, the thread being passed from the drawing-rollers through an eye and under the first ring and over the second to the spindle cup or bobbin, as and for the pur- 2o pose set forth.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
